摘要：

This Paper investigates the magnetic integration of a resonant push-pull converter operated at a switching frequency in the high frequency (HF) range (3-30 MHz). Based on the requirements arising from circuit considerations, a magnetic structure is derived that is suitable for integrating all the necessary inductive elements into one single component. An experimental demonstrator of a resonant push-pull converter operated at a 6.78 MHz switching frequency is used to verify the applicability of the proposed structure. The demonstrator features precise resonance tuning and has an output power of 420 W at the rated operating point with a dc-dc efficiency of 91%.
